Question

hat is the term for a change in direction of a wave as it changes speed while moving from one medium to another?
transmission
reflection
absorption
refraction

Explanation:

• Transmission: Wave passes through medium without significant change in direction.
• Reflection: Wave bounces back from a surface.
• Absorption: Wave's energy is taken in by medium.
• Refraction: Wave changes direction as it changes speed when moving between media (e.g., light from air to water).

Answer:

refraction
